I want to grow some Celeriac and wonder if the southern heat in the summer will affect its growth. I live in Columbus Georgia and celeriac is not known down here. Also, if I sow in January, will the frost affect it?

Being as Celeriac is a root crop, it can easily handle Winters in Georgia, IMO. I live in Port Angeles, WA, and I grow Celeriac all year around. However, I do use about 4" of Alder wood chips. Works great at keeping everything nice and cozy. :-)

How do you know when the celeriac is ready to harvest?
17 Mar 17, John (Australia - temperate climate)
Harvest celeriac when the stem is 75-100 mm (3-4") across or before a heavy frost is likely.

Would like to try growing celeriac, I live on the Whangaparaoa Pen., Auckland, wonder if it would grow here or if wrong climate? Also, if ok, which variety would grow best here.....am trying to lose weight and read celeriace chips better diet option than potatoes? Many thanks, Ruth.
